I know right? My main issue/source of bafflement with this doujin is how the actual plot is very interesting and the newer characters pretty thoughtful, but the three humans all have their most memey and annoying personalities. I mean, villainizing them was definitely an intentional choice story-wise, but this level of exaggeration is just grating and I try my best to ignore it because I like the rest.
Admit it, if you had the power to reset stuff, you would abused it for all what is worth.
Depends on if it was groundhog day-type scenario or "reverse short while back" kind of scenario. Groundhog day would be hell on earth after a while and would eventually end with you doing every thing imaginable. This is a bit different and since you really don't know if there is a limit to the rewind time of death effect you wouldn't be as likely to push it in the potential case it might wear off.
